Duclos

Duclos is a surname of French origin. It is typically interpreted as a toponymic or descriptive name derived from the phrase du clos, meaning “of the enclosure” or “from the enclosed place,” with clos referring to a fenced field, courtyard, or similar area. As such, the name likely originated to indicate residence near such a feature. The surname is found in France and in other French-speaking communities, including Canada and parts of Africa through historical migration and colonial ties.

Notable people with the surname include Jacques Duclos (1897–1975), a French communist politician who was a prominent figure within the French Communist Party and active in parliamentary life during the mid-20th century. Beyond this, individuals bearing the name have made contributions across various fields, including politics, academia, and the arts, reflecting the name’s long-standing presence in Francophone societies.

In encyclopedic use, Duclos is primarily recognized as a family name. It may also appear in toponymic contexts or in references to people bearing the surname, but it does not point to a single widely known non-surname entity.
